I was wondering if there is any possibility (jscript, actions, etc.) to automate RFC3161 timestamps for PDF/A documents. For technical reasons here in Germany I need to separate a qualified electronic signature (provided by our new ID-Cards) and a timestamp, as the former (for whatever stupid reason) does not support timestamps. It would thus be very convenient if I could batch process all PDF/A files in a certain folder and apply an RFC3161 timestamp. The signature needs to be applied with another program (as our ID-cards are not compatible to Acrobat).
